Be it known that we, ALLAN A. ADAnisoN and WILLIAM F. Gnnrn, citizens kof the United States of America, residingr'at Brooklyn, county of Kings, Stateofhl'e'w York, Hudson Heights, county of Bergen, State of NewnJersey, have invented .certain new and useful Improvements in Methods of Producing Rim Boards, of which the following is a specification. v

The invention relates to a methodof pro- .y

ducing rim boards and more,pz'i'rtie'ularly` to the method of producing riml boards fer bfuilt-up paper boxes or containers, Ysuch ,r1-m

boards havingi'inish paper appliedrther'eto.

The invention comprises direetingpaper board, or the equivalent and directingnish paper kinproximity thereto, applying the `finish paper to the board, with theuse of adapted to iit the neck. p As an example of one manner of Carrying .out the invention, we now describev the production of a rim boardsuitable to be lCombined with `a bottom to f-orin a tray g'lhowever, it will be understood that such rim board is also capable of beingcombined with the top to form the cover and for the` sake of brevity, it will be understood that theterm rim as employed hereinafter, applies ,to that of` the cover as well as to that of the tray, and that the 'term bottoinapplies also to the top. y f

in the usual rim ofsuch paper container, the finish paper is applied to a flatface, turned over at a longitudinal edge Yandaffixed to such portion ofthe opposite flat face as may be desired. vThe iini'sli,pa} ier also extends laterally of the strip to-form an extension having its greater dimension in the direction of the length of the strip. Such extension, upon folding the strip to produce the rim, is aixed to the bottomA speciieatieii of Letters rateiit.

and serves-to' hold'v the bottom. to `the rim,

s l y board .may be supp liedl from a reel' ofindeiinite length, and similarly the finish paper, the width of the latter providing forI the desired width of the lateral extension. The board and finish paper are brought together and the finish paper applied to the board,l and afiixed thereto by theuseof any lsuit-abley adhesive.v

llilurther features, and objects of the inven- ,tionwill be more fully. understood from the following description and the accompanying drawings, in. which- Fig.' l is adiagrainmatic perspective view,

The C'Qmbiaed masi-miie length if board andiinish' paper applied thereto is run in `flat jposition toward, the circular cutter 9,

4asindicated' in Fig. 2, or equivalent, and severedthereby in a plane substantially perpendicular to the, ,fiat faces 8,` l0 of the board, yielding a strip ll of board having `the finishvpaper applied thereto. The length ofy'j'th'e strip llnsdeternined bythe perimeter of thestri-p 'when folded and positionedas apart ofthe article in Awhich it is lto' be incorporated.

In Fig.- 4, We have indicated such strip 11 forming the rim of a tray 13 of a built' up paper box such as a cigarette box.

.As will be noted from Figs. 2 Aand 3, the severed strip 11 of board with the finish paper applied thereto, has its two opposite ends 14, 15 squared and the opposite edges at both ends ofthe finish paper 3` extending substantially co-incident with the fsquared ends 14, 15.

Theresulting product 13, such as a tray of a box embodies thev severed strip 11 as its rim, the ends 14, 15, forming butt ends Yand the extension 6 of the finish paper being applied to the four'peripheral portions of the bottom piece 16, thereby holding the rim 11 vinv position, and the ends 14, 15 immediately abutting one another. The extension 6 of the finish paper serves also vto finish the `face of the bottom piece 16.

The severing of the indefinite length of rim strip effects clean'ends of the combined board and finish paper,y affordingy a product of ya high degree of i artistic appearance.

The severing, to provide forthebutt ends of the strips, is .performed rapidly and accurately, and entirely eliminates waste.

The rim of the tray thus formed possesses the full required degree of strength.

'The cutting may be performed manually,

but for attaining speed the cutting isusually performed by means of a mechanically operated, severing or punching device.

.'For obtaining a strip having the straight ends, the severing is expeditiously performed by means of a power operated, circular knife, such as described in our coending application `'Serial No.240,426, filed une 17, 1918, entitled Rim boards.

Our invention is f advantageously carried cutby feeding the board from a reel-,and similarly feeding the' nish `paper from a reel.

` Such straight end strip may bel utilized in the forming of the rim as a butt strlp, i. e., the opposite ends upon folding the strip abutting one another, inl which; case the lengthof the strip is approximately the perimeter of the folded rim; or such straight ended strip may be utilized `as a lap strip,

i. e., the opposite end portions of the strip i l upon folding the strip lapping one another,

in which case the length of the strip exceeds the perimeter of the rim bytheextent of the lap.

The invention is advantageous that the operation of applying the continuous length of finish paper to continuous length ofthe V board reduces the period of the stage of affixing one to the other and also reduces the specification this 11th day of June, 1918.

portant advantage of producing strips havn and box parts.

lrelation, feeding'a continuous length of fin ing finish paper aflixed thereto but free from any tab or tabs of the finish paper, in other words, the finished strip is without any tab tirely overcomes the delay due toV the interference of the prior art tax strips in 0b- `structing the parts of the box producer, conveying adhesive to the parts and. by being 7 5 torn off and dropping in the box producer.

The invention results in materially reducing the number of defectively formed boxes Whereas we have described our inven- S0 tion by reference to'specific methods, it will be understood that many changes and modifications may be made without departing from the invention as defined by the append. ed claims. i
